This invention relates to improvements for machines for making ice and has as its 10 special object the provision of a compact apparatus which may be installed in a dwelling or otherplaces where a supply of ice is desirable..

.A further object is to provide 5 means t5 wherebya spray of water is formed into ice by the use ofsuitable chemicals arranged in a,casing enveloping the spray chamber, and which canbe removed therefrom in piecesin a convenient manner.

so These and other like objects are attained by the novel construction of parts herein-'1 after described and shown inthe accompanying drawing, forming a material partof this specification; andin which- Figure 1 is avertical sectional view showing an ice machine made in accordance with the invention, l

Fig. 2 is a horizontal sectional view taken on line 2'42 of Fig. 1, arid I to Fig. 3 is a fragmental vertical sectional view showing the arrangement of parts.

A chamber 10, here shown to be rectangular; is provided with. a cover '11, andsup: orted by columns 12, on any, sui ble level t5 oundation and inclosed within the' hamber 10, juxtaposed to the side walls thereof, is a tit hollow casing'14 through which is .circufl fr lated a volatile. refrigerant or brine in the.

usualmanner, instead of-which a freezing no mixture may also be used which is renewed from time to time'as'themixture 'becomes exhau sted', and said volatile refrigerant or freezing mixture are supplied to the casing through a pipe '15. 1 at Entering the ch'amberis'h water pi same terminating in an} elbow 18, in the other opening of which is engaged a downwardly extending pipe 19, passlng through the'disk 20, which. is engaged within a 1'0? t tating head 22, from which leads four; tubular branches 23, these provided with a plurality ofsperfbrations 25, the same being directed toward the upper part ofthechamber 10, thetubes having caps 26 at their ends, so

as to force the current of incoming water Specification or Letters Intent.

entering from the'pipe l7, outward in the form of a spray within the-chamber 10.

' Opposite to the inlet 20, in the head 22, is

secured a vertical shaft 28, the same extending through the bottom of the chamber 10, and being rotatably mounted in a bracket '29, immediately above which is secured a pulley 30, drivernby a belt 31, from another pulley 32, mounted on a vertical shaft 33, housed in a support bracket 34. At the upper end ofthe shaft 33, isagear 37 connecting with the mating gear 38, the same being secured upon the shaft 40, of a motor 42, mounted upon the bracket 43, secured to the foundatlon.

.Upon the motor 42, being energized,

power will be conducted through the shaft 28, causing the spray headto rapidly rotate within the chamber 10, forcing the spray upon the inner walls, so that the ice is rapidly formed upon its inner sides and which is through the perforations25, so as to' strike accessible by raisin the door 11 and removq mg the ice in an o vious manner. It being understood that water is supplied'through the pipe 17, and so long as the. motor is kept in operation, ice will be formed and caused to adhere to the inner walls of the chamber to any desired thickness.

Having 'thusflescribed my invention what I claim as new and desire\to secure by Letters Patent is, I 1 e In an apparatusfor. producing ice of the character described, the combination of a casing, a jacket in said casing adapted to be supplied with d volatile refrigerant, or a eezing mixture for circulation therein, a

a central ice chamber in saidca'sing, a water supply pipe for'said chamber, a disk secured to the inner end of said pipe, a rotating head in engagement with said disk, four tubular ebranches arranged to form a cross 7 formed with said head and provided with a plurality of perfofations-dlrected toward theupper supply pipe for said refrigerating medium,

part of said chamber, caps at the, ends of said ranches, a tubular shaft secured to the head at a point opposite to-said disk, extending through the casing, a bracketin which the tubular shaft is rotatably mounted, a motor, and means for rotatingsaid shaft from said motorm I Y -signature. E v
